Therefore, it is better to see the power increase in each communication. The heat dissipation requirements of each communication.

In the same way, (the air inside the communication and the communication outside each other) is also relatively small in heat dissipation, and the heat dissipation can increase the surface of the outer surface of the thin heat pipe (the first heat dissipation pipe and the second heat dissipation pipe).

Wherein, the upper end of the second group of heat-dissipating tubes is not lower than the upper end of the first group of heat-dissipating tubes, and the second group of heat-dissipating tubes is not lower than the group of tubes

The external heat flow of the second group of heat-dissipating thin tubes is exchanged, so that the steam in the two sets of heat-dissipating tubes is exchanged, and the heat-dissipating tubes of the second group of heat-dissipating tubes flow through the second group (ie, the second group of heat-dissipating tubes in the second group) Under the pipeline, the flow pipe is the lower flow pipe, and the flow is the first group of heat dissipation pipes)

According to the above, Hugh in the first group of heat-dissipating thin tubes and the second group of heat-dissipating thin tubes to take off steam in the first group of heat-dissipating thin tubes, steam flow tubes, the second group of heat-dissipating tubes and the tube in the formation of the rest tube, and communicate with each other .
